Aquatic Experts Bonded Aquarium Filter Pad, 12x72x.75 in, Cut to Fit | Bonded filter pad lasts 2x longer, cuts to fit any filter, for freshwater, saltwater, and reef tanks.

Great value. Works perfect in my filter. Cheaper than buying the pre-made filters.

Love this stuff! Works great and it's pretty thick also which is nice. Easy to cut and put in your filter.

I cut these up into squares so that they’ll fit into my bio cube filter. And it works great. I mean this whole thing might last me a whole year it’s so much. And I just replace it out every week and it’s amazing what it catches and it’s really reduced the amount of garbage in my fish tank as well as reduce the amount of bubbles coming out of my protein skimmer that end up in the tank. So yes a great purchase I’m just gonna be buying this for the rest of my tank’s life.

Works great. I'm using blue side up as someone suggested...

Keeps the water crystal clear.

This is my second time purchasing it. It works well.

Does what it is supposed to, filters large fragments of water ever is on the aquarium. Thickness is good and able to cut to fit. Wash it out a few times and reused it so that the roll would last longer. Doesn't fall apart even after washing so it's pretty sturdy.

Exactly what is advertised
